<p>PCT No. PCT/SE90/00674 Sec. 371 Date Jun. 5, 1992 Sec. 102(e) Date Jun. 5, 1992 PCT Filed Oct. 19, 1990 PCT Pub. No. WO91/06732 PCT Pub. Date May 16, 1991.Seal preferably intended to be used for door locks on motor vehicles. The seal comprises an annular base part, an annular combined sealing surface made up of a first part surface and a second part surface which intersect at an intersection region at an angle beta , and an annular flexible element connecting the base part with the combined sealing surface. The seal is arranged such that, for example, when a vehicle door to which the lock is fitted is in a non-sealing position, the first part surface of the combined sealing surface forms an angle alpha in relation to a plane A-A which is parallel to the part of the door which is to be sealed. When the door is closed, the second part surface of the combined sealing surface is acted upon by a region of the door to thereby cause the first part surface of the combined sealing surface to adopt a position substantially parallel to the plane A-A such that an annular area of the surfaces on the part of the door is sealingly enclosed by said combined sealing surface.</p> |
